Tane Ikai(猪飼 たね,Ikai Tane?, January 18, 1879 – July 12, 1995)[2] was a Japanese supercentenarian who was, at her death, the oldest person ever from Japan. She was the first person from Japan verified to have celebrated a 116th birthday.[citation needed]

Tane Ikai was born on January 18, 1879 in the village of Kansei, Aichi Prefecture (now part of Minato-ku, Nagoya). She was the third daughter of six children of a farmer family. She married at age 20, had three sons and a daughter, and separated from her husband when she was 38 in 1917. She entered a nursing home at the age of 89 in 1968. In 1988, at the age of 109, she suffered a stroke and was moved to a hospital, where she remained bedridden for the rest of her life.[1]

Ikai became Japan's oldest person at the age of 113 in 1992 following the death of 114-year-old Waka Shirahama. She outlived all of her children and died on July 12, 1995, aged 116 years and 175 days. An autopsy indicated that she died of kidney failure.[1]
